我想实现资源数据结构包括一个数组的数组，特别是字符串。我遇到的问题是如何让子阵列对象及其具体数值。这里是我的资源文件看起来像......

I am trying to implement a resource data structure that includes an array of arrays, specifically strings. The issue I run into is how to get the sub-array objects and their specific values. Here is what my resource file looks like....

<resources>
   <array name="array0">
     <item>
       <string-array name="array01">
         <item name="id">1</item>
         <item name="title">item one</item>
       </string-array>
     </item>
     <item>
       <string-array name="array02">
         <item name="id">2</item>
         <item name="title">item two</item>
       </string-array>
     </item>
     <item>
       <string-array name="array03">
         <item name="id">3</item>
         <item name="title">item three</item>
       </string-array>
     </item>
   </array>
</resources>

于是，在我的Java code我找回阵列和尝试访问的子元素，像这样......

Then, in my Java code I retrieve the array and try to access the sub elements like so...

TypedArray typedArray = getResources().obtainTypedArray(R.array.array0);

TypedValue typedValue = null;

typedArray.getValue(0, typedValue);

在这一点上typedArray对象应重新present字符串数组array01，但我看不出如何检索ID和称号字符串元素。任何帮助将是AP preciated，在此先感谢。

At this point the typedArray object should represent the string-array "array01", however, I don't see how to retrieve the "id" and "title" string elements. Any help would be appreciated, thanks in advance.

推荐答案

您几乎可以做你想做的。你必须单独申报每个数组，然后引用数组。事情是这样的：

You can almost do what you want. You have to declare each array separately and then an array of references. Something like this:

<string-array name="array01">
    <item name="id">1</item>
    <item name="title">item one</item>
</string-array>
<!-- etc. -->
<array name="array0">
    <item>@array/array01</item>
    <!-- etc. -->
</array>

然后在你的code，你做这样的事情：

Then in your code you do something like this:

Resources res = getResources();
TypedArray ta = res.obtainTypedArray(R.array.array0);
int n = ta.length();
String[][] array = new String[n][];
for (int i = 0; i < n; ++i) {
    int id = ta.getResourceId(i, 0);
    if (id > 0) {
        array[i] = res.getStringArray(id);
    } else {
        // something wrong with the XML
    }
}
ta.recycle(); // Important!
